You don't need to change the file extension, just a build setting. Change "Compile Sources As" from "According to file type" to "Objective C".
Also, I've found that "@" as in @"String Constant" produces Bison confusion. I use a #define so that I can write AT"String Constant".

I do see that bison can generate C++ instead of C. Does anyone know whether there is any version of yacc or bison that has been modified to generate Objective-C? Or if there is any other parser generator available that can generate Objective-C.

That means that could be Objective-C code - you'd only need to change the file extension from .c to .m to compile it. As long as the emitted code is the only Objective-C and therefore not required to be parsed by YACC, I reckon it ought to work.
